A case report of a malignant eccrine poroma metastasizing to long bones is described. This rare tumor of intraepidermal eccrine sweat duct origin usually metastasized to visceral organs. This is the second reported case of bone metastasis. Although a hip disarticulation was performed for ipsilateral femoral and tibial metastases presenting seven years after resection of the primary tumor, this 43-year-old man died six months later, from pulmonary metastases.
